From: Aspirin decreases the risk of depression in older men with high plasma homocysteine
Odds ratio (OR) of depression among older men according to their plasma concentration of homocysteine (tHcy⩾15 μmol l−1 compared with <15 μmol l−1), use of aspirin (yes compared with no), B-vitamins (yes compared with no) and the interaction between high plasma homocysteine and use of aspirin or B-vitamins. Older men with high tHcy using aspirin had lower odds of depression (OR=0.57; 95% confidence interval (CI)=0.36–0.91). Results of the multivariate logistic regression were further adjusted for smoking status, Charlson index grouping and use of antidepressants (other variables, including age, did not contribute significantly to the results of the model).
